DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjustment system suitable for adjusting gamma, color temperature, etc. of a plurality of video display devices arranged to form a large screen.

[0002]

2. Description of the Related Art One of the methods of forming a large screen in a place where a large number of people can see it, such as various exhibition halls, and displaying an image is to use a plurality of image display devices in a vertical or horizontal direction. In other words, there is a method of arranging them in a wall shape and displaying an image with the entire screen of the image display device as one screen.

In such a plurality of video display devices arranged in a wall shape (hereinafter, also simply referred to as "walls"), in order to maintain good image quality, color variations do not occur between the video display devices. In addition, it is necessary to adjust gamma, color temperature, and the like of the image display device.

In a conventional wall, adjustment of gamma, color temperature, and the like is performed by any of the following methods (a) to (c). (A) An operation for adjusting gamma, color temperature, and the like is performed on a control panel of each video display device main body. (B) A remote controller with an index key capable of individually selecting a plurality of video display devices, an operation of selecting individual video display devices on the wall, and adjusting gamma, color temperature, and the like of the selected video display devices. Perform operations. (C) A personal computer on which software for adjusting gamma, color temperature, and the like of the video display device is installed is connected to the video display device via a serial port (for example, an RS-232C port), and the personal computer is operated. .

[0005]

However, in the above method (a), the operator has to move to the image display device to be adjusted one by one to perform the operation. It will take.

In the method (b), since the correspondence between the operation of the index key and each image display device on the wall is not easily intuitively understood, the key operation is complicated and the key operation is difficult. There is a possibility that gamma, color temperature, etc. of video display devices other than those to be adjusted may be adjusted by mistake.

In the method (b), the adjustment operation can be performed only in the vicinity of the wall (in a range where the signal of the remote controller reaches).

In the method (c), software (for example, in the case of RS-232C, a synchronization method, a data transmission speed, a data length, a parity, etc. Must be created in order to make the communication with the video display device), and it takes time and effort to create the software.

Also, in the method (c), the adjustment operation can be performed only in the vicinity of the wall (the range where the serial cable connecting the personal computer to the video display device can reach).

Further, according to the method (c), if there is a bug in the software, in order to correct the bug, the software without the bug must be re-installed on the personal computer at the installation location of the wall or a patch must be installed. You have to hit it (replace the program code and modify the software). Therefore, it takes time and effort to fix software bugs. In particular, when the wall is installed at a plurality of different locations, such repair work must be performed at each location, which requires much trouble and time.

[0011] In view of the above, the present invention provides a method for displaying a video by arranging a plurality of video display devices in a wall shape.
Adjustment of individual video display devices can be performed easily, quickly, intuitively and easily, and at a location away from the wall. The task of fixing the bug is to make it easy and quick.

[0012]

In order to solve this problem, the applicant of the present invention has proposed a method in which a plurality of video display devices arranged vertically and / or horizontally, a server, and an operation terminal are connected via a network. Each video display device is provided with communication processing means for performing protocol conversion between a communication signal that can be processed by the video display device and a communication signal that can be transmitted over a network. In order to adjust each video display device based on an operation on a GUI (graphical user interface) screen, software for communicating with each video display device via a network is installed. Proposes a video display device adjustment system in which a browser for browsing the GUI screen is installed.

In this adjustment system, a plurality of video display devices (that is, walls) arranged in a vertical and / or horizontal direction, a server, and an operation terminal are connected by a network.

Each video display device on the wall includes communication processing means for performing protocol conversion between a communication signal that can be processed by the video display device and a communication signal that can be transmitted over a network.

In the server, software for communicating with each video display device via a network in order to adjust each video display device based on an operation on a GUI screen is installed.

A browser for browsing the GUI screen is installed in the operation terminal.

In order to adjust a certain video display device on the wall with this adjustment system, this GUI screen is displayed on the operation terminal, and an operation for adjusting the video display device is performed on this GUI screen.

Then, communication for adjusting the video display device is performed via the network between the server and the video display device. At this time, the communication processing means provided in the video display device performs protocol conversion between a communication signal that can be processed by the video display device and a communication signal that can be transmitted through a network.

Then, the processing based on this communication is executed by the video display device, so that the video display device is adjusted.

As described above, the individual video display devices on the wall are adjusted by operating the operation terminal. Therefore, unlike the case where the control panel of each video display device main body of the wall is operated as in (a), the adjustment operation can be performed easily and quickly.

The operation of selecting an individual video display device on the wall on the GUI screen is the same as the operation of selecting an individual video display device on the wall by operating the index key of the remote controller as in (b) above. It can be different and intuitive.

Further, since the individual video display devices on the wall are adjusted by operating the operation terminal connected to the individual video display devices on the wall via the network, the methods (a) to (c) described above can be performed. In contrast, the adjustment work can be performed even in a place away from the wall.

As the software to be installed on the server, it is sufficient to create software that performs communication using a standard protocol of a general-purpose network. Therefore, unlike the case of creating software that performs communication using a specific protocol that can be processed by the video display device as in (c) above, creation of this software can be performed easily and quickly.

If there is a bug in this software, to fix the bug,
You only need to reinstall the bug-free software on the server or patch it. In particular, even when a wall is installed in a plurality of different places and a plurality of operation terminals are provided in one-to-one correspondence with the walls, such correction work is performed only in one place where the server is installed. I suffice. Therefore, unlike the case where the repair work is performed at the installation location of the wall as in (c) above, the software bug can be easily and quickly corrected.

As an example, the software installed on the server is to display the icons of the respective video display devices on the wall on the GUI screen in a positional relationship corresponding to the arrangement position of the video display devices on the wall. Is preferred.

As a result, the operation of selecting an individual video display device of the wall on the GUI screen becomes very easy and intuitive.
